Application led November 9, 1912. Serial No. 730,393.

To all wzomz'zfmag/ concern;

Be it known that I, HERBERT'FLEnTwooD I HoLwonTHY, a subject of the King of England, residing at Church Stretton, Salop, England, have invented certain new and useful Improvements in Wheel-Scotches, of whichthe following is a specification.

This invention relates to scotches for the wheels of vehicles; it is applicableto varlous kinds of vehicles, but is particularly useful for motor vehicles to prevent slipping on a slope when a wheel is jacked up for tire changing. If a puncture to a pneumatic tire occurs on the front wheel, 4it is usually practicable to `secure the vehicle4v by locking the back wheels with the hand brake which can be fixed on; when, however, t-he puncture occurs on one of the back wheels this cannot be done as the wheel which is jacked up must be free for turning purposes in order to allow of the manipulated.

According to the present invention there is provided an improved form of wheel scotch which readily folds up, andwhich preferably has an angularly-adjustable wheel-engaging member, whereby the scotch may readily be adjusted lar size or form of wheel be used. 4

Conveniently the scotch comprises a wheel-engaging member hinged to a base plate and adapted to be held in varying angular relation thereto For a more complete understanding of the invention, reference is directed to the accompanying drawing, which shows, by way of example, one form of scotch according to the-present invention.

In this drawing Figure 1 is a perspective viewof the scotch with the wheel-engaging member .in working position. Fig.A 2 is an under-plan view of one form o base plate, and Figg is a side elevation with part of one side flange of .the base plate broken away, showing the parts folded up.

` Like letters of reference refer to like parts throughout the drawings.

In the .construction shown, on a base plate A therer is hinged awheel-engaging member B, a pin A4 holding the two members together. vThe member B is preferably curved as shown in Fig. 1, the better to fit the tires or wheels in connection with which it is to be used. The base plate A is formed on its under side with side anges A2 which Vwith which it is to tire being conveniently to suit the particu-- by a suitable support.

'the parts will all lie maybe serrated or toothed as shown in the rawings to get a Good grip on the ground. Toward the heel. b i may also be provided an additional grip- Ding strip A3 which also may be serrated if desired. f

Hinged to the member B is a support or strut C which may convenient-ly be taperedv as shown, and

the end of which engages rack teeth A4 formed on the upper face of the base plate Agithus, by changing the position of strutC in the gular relation of the members A and B may be adj usted as desired. y The plate A and member B are preferably slotted or perforated as shown at A5 and B for the sake of lightness.

en it is desired to scotch up a wheel, all that is necessaryis to adjust the member B to a convenient height and then push the scotch into engagement with the wheel in the well known manner. lVhen the 'scotch is not in use the member B should be folded over on to the under face of the base plate as shown in Fig. 3 to t between the side flanges A2 the strut C should also be folded down to the base of the member Bso that flat and take up little room. y

`While Aone scotch as above described -will holding the car on a slope, when the puncture takes place on the level it is difficult when .pulling the tire and wheel about tol avoid pushing the car off the jack, and trouble may readlly arise. To prevent this thescotches may be used in pairs, one in front of the wheel and one behind it; when such should be connected together by a chain D or a rod or the equivalent, so that they may be kepttogether and one of them will not be left on the road by oversight-in other words, so that when one scotch is removed the other must also be removed. When a pair of scotches is thus employed, it is preferable to serrate the portions A2 and A3 on the base plate on only one scotch, which should be placed into position first. The other scotch, with unser-rated strips A2 and A3 can then more easily be pushed into po-l sitlon.

For lightness it is lpreferred to stamp the parts out of steel, but they can be cast from aluminium or otherwise produced as de-` sired. When folded up the scotch takes up very little room and can be easilycarried in rack teeth A4 the ani a pair of scotches is used Vthey of the base plate Athere a wheel engaging mem and arranged to be folded' the toolbox, or it may be hung Aupon a hook or other support convenient for-use. The size, strength, and weight of the parts may be varied to suit circumstances, as the'scotch is equally useful for small or for heavy vehicles.

For application to twin tires, the scotch may be formed double, and if desired, with hollows to receive the tires; also the top plate may in any case be hollowed aswell as, or without being curved to the circumference of the wheel. y y

The scotch may be rovided with an adjustable'or Vxed 'handlle by which to place it in the wheel.

Obviously the strut C andrack teeth A4 may be modified as desired or be substituted by equivalent parts. For instance the strut may be hinged to the plate` A and therack teeth formed in the member B, or a pin engaging in holes may be substituted for the strut and rack teeth shown in the drawings. If desired also the base plate A maybe omitted and the strut C en age directly with the. ground. Other modi cations may also be used, and it is to be understood that the lspecic construction shown inthe drawings is only given by way of example and that the invention is not limited thereto.

What I claim as my invention and desire tosecure by Letters Patent is 1. A wheel scotch com rising a base plate, er vpivoted to the frontend thereof on the under side of the base plate when not in use, a support engaging the base plate and wheel engaging member when open for use, and means for retaining said support in position with relation to the base plate and wheel engaglng member; substantially as described.

2. A whe'elscotch comprising a base plate having downwardl extending hinged pro- 'ections 'at one en thereof, a wheel engaging member pivoted to the front end of the vhinged projections,

tween the flanges of the base plate,

base plate and arranged to be folded on to the bottom of the base plate, said wheel engaging member having reversely extending a rack on the v upper face of the base plate, and a support pivoted to the wheel engagin member and arranged to engage the teeth in the rack to' hold the -wheel supporting lmember in its proper position with relation to the base; substantially as described.

3. A wheel scotchl comprising a base plate having serrated anges along its longitudilnal edges andon the lower face thereof, a wheel'engaging member pivoted to the front end thereof and arranged to be folded so as to lie onf the bottom of the base plate beand a support pivoted to the wheel engaging member and arranged to engage the base to retain the wheel engaging membervin proper position when the scotch is in use; substan-` tially as described.

4. A wheel scotch comprising a base plate havin serrated flanges along its longitudinale ges andon the lower face thereof, a wheel engaging member pivoted to the front end thereof, said wheel engaging member having-a face for engaging the wheel when -in use and arranged to be folded so as to lie on Athe bottom ofthebase plate between the flanges of the base plate, there being a rack on the base plate, and a supporting member pivoted to the wheel ranged to -enga e the teeth in said rack to retain the whee supporting member in position with relation .to the base plate when the scotch is in use; substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. y
